Homework Questions? View Answer Key  Quiz Questions?

Roots can look like… Now its your turn to draw a parabola that describes each type of roots: Sketch a parabola with 2 real roots Sketch a parabola with one double root Sketch a parabola with no real roots

RECAP OF ROOTS 1 Root 2 Roots No Roots Vertex is on the x-axis Answer is vertex! (x,0) No Roots Does not cross x-axis Vertex is above and opens up Vertex is below and opens down Answer: None 2 Roots Crosses x-axis twice Vertex is below and opens up Vertex is above and opens down Whole Numbers Answer: (x,0) and (x,0) Between 2 Numbers Answer: # < x < # # < x < #

X-intercepts X-intercepts are also called… Roots! Integral Roots: In between two integers on the x axis

Recap… What is the y-intercept?.... State the y-intercept:

Let’s play… Check it.. 1,2,1,2!!

Check it 1, 2, 1, 2… and pass it back! Label a, b, and c. Does the parabola open up or down? Max or min? Solve for the axis of symmetry Solve for the vertex Graph the parabola (use magic ordered pairs) Label the roots and y intercept of the parabola.
